Procedure

A mixture of 1.2 g. of 1-phenyl-2-amino-4-oxo-2-imidazoline, 15 ml. methylene chloride and 3.6 ml. of methylfluorosulfonate was left to stir at room temperature for 20 hours. The reaction was stopped and filtered to give 1.9 g. (94%) of the acid salt of the product. The isolation of the free base (m.p. 164°) is made by treating the salt with aqueous sodium hydroxide.
